However, the situation in not homogenous in our country. Aim: To determine the incidence of stroke in the Health Service South Araucanı´a (HSSA) during the period 2001–2010. Methods: The research is a descriptive Cross-Sectional Study. The study considers the databases of the department of statistics and health information (DEIS) for the years 2001–2010. The population over 15 years who presented an episode of stroke it was considered during the period 2001–2010, which received attention in the HSSA, and its principal diagnosis agree to the criteria of ICD-10. Results: During the study period was obtained 6548 hospital discharges. There were no significant differences between men and women, in the discharge.The most frequent diagnoses were for male and female ischemic or hemorrhagic stroke and then the intracerebral hemorrhage (ICH). The incidence rate as a condition of discharge and type of stroke was 961.3 (95% CI 950.7 to 972.4). Both men and women, the highest percentage were hospitalized between 1–10 days (75%). The mortality rate at discharge was 18.2%. Conclusions: The information collected allows complement and have an updated regarding the incidence of stroke in different health centers in our region, the fifth most populous in Chile, with geographic, ethnic characteristics and social own perspective. The incidence rate is higher that we have on PISCIS study (Iquique, Chile) and is very close to Bulgaria. The mortality rate is within the norm for middle and high income.
